This is a great educational "toy". What is 6 +7? If the child thinks he/she knows, they just press the button and it pops up with "13" on the side.
Condition - Very good used. Clean with no damage, except one button (9+8) has a scratch on the top, but it is still visible and usable - see the picture.
